The pilot stated that while on approach he increased his airspeed due to turbulence. The airplane landed hard and bounced. He added power to abort the landing, but realized that he could not climb over the trees at the end of the landing area and closed the engine throttle. As the airplane touched down again it continued off the end of the site and collided with brush. The pilot said that there were no mechanical problems with the airplane and that he should have used a slower approach airspeed or performed a go-around earlier in the landing. The airplane sustained substantial damage to the left wing spar and aileron. ## Factual narrative The pilot was landing at an off-airport site, which was surrounded by trees.
